问快速将多个值赋值给类中的“`this`”

EN

class Foo {
  constructor(firstName, lastName, age) {
    const fullName = firstName + lastName;
    const age = age * 5;

    this.fullName = fullName;
    this.age = age;
  }
}

class AudioPlayer {
  static init() {
    const audio = new Audio();
    audio.loop = true;
    audio.autoplay = true;

    const audioFiles = {
      slow: 'mp3/slow.mp3',
      medium: 'mp3/medium.mp3',
      fast: 'mp3/fast.mp3'
    };

    audio.src = audioFiles.medium;

    const audioContext = new (window.AudioContext || window.webkitAudioContext)();

    const audioAnalyser =  audioContext.createAnalyser();
    audioAnalyser.fftSize = 1024;

    const audioSource =  audioContext.createMediaElementSource(audio);
    audioSource.connect(audioAnalyser);
    audioAnalyser.connect( audioContext.destination);

    const bufferLength = audioAnalyser.frequencyBinCount;

    this.audio = audio;
    this.audioFiles = audioFiles;
    this.audioContext = audioContext;
    this.audioAnalyser = audioAnalyser;
    this.audioSource = audioSource;
    this.bufferLength = bufferLength;
  }
}
